Hello Mario Kasi,

I understand your frustration, but there's not much that can be done. Your files have been compromised by a variant of Dharma - a high-end ransomware infection. Unluckily, restoring data from backup (if you have one created) is probably the only possible solution. You should, however, still try RakhniDecryptor developed by Kaspersky. It is capable of cracking encryptions performed by certain Dharma's variants. Nonetheless, the chances are very slim.

File encryption performed by such high-end ransomware infections is impossible to crack. That is of course if the encryption has been performed flawlessly. The decryption requires a unique key generated individually for each victim. The problem is that cyber criminals often ignore victims once the payments are submitted. In fact, it is very likely that these persons do not even have the generated keys, as none of them are being saved. They simply trick victims into paying and give nothing in return. If he will respond you asking for an additional payment - DO NOT agree to pay. You'll just lose even more money and your data will remain encrypted.
